This is the fourth edition of the industry-acclaimed OpenStack Cloud Computing Cookbook, created by four recognized OpenStack experts. It has now been updated to work with the latest OpenStack builds, using tools and processes based on their collective and vast OpenStack experience. OpenStack Open Source Cloud software is one of the most used cloud infrastructures to support a wide variety of use cases, from software development to big data analysis. It is developed by a thriving community of individual developers from around the globe and backed by most of the leading players in the cloud space today. We make it simple to implement, massively scalable, and able to store a large pool of data and networking resources. OpenStack has a strong ecosystem that helps you provision your cloud storage needs. Add OpenStack's enterprise features to reduce the cost of your business.

Common OpenStack orchestration tasks


This section outlines a number of common tasks using the OpenStack Orchestration (Heat) service to launch stacks (orchestrated environments using Heat). For more information on Heat and orchestration, refer to Chapter 9, OpenStack Orchestration Using Heat and Ansible.

Getting ready

Ensure that you have the OpenStack clients installed, as described in the first recipes of this chapter.

How to do it…

Carry out the following steps to create and use Heat templates in OpenStack to create orchestrated environments:

Launch a stack from a template and environment file

To launch a stack from a heat orchestration template (hot), issue the following command:

openstack stack create
    --template myStack.yml
    --environment myStack-Env.yml
    myStack

Listing stacks

To list the running stacks, issue the following command:

openstack stack list

Deleting a running stack

To destroy a running stack named myStack, issue the following command:

openstack stack delete myStack
